what keeps killing ignition boxes

Can a Mopar orange box be benched tested ?

Can a Mopar orange box be benched tested ?

I imagine it would be tough to test without special test equipment.

that sounds a bit on the high side to me. I'm usually looking for about 13.5-14v. I suspect that when a load is applied such as the headlights, the voltage spikes higher which causes the current to rise as well. That'll blow the ecu and ballast if it goes high enough.

what is the resistance (ohms) of the coil? disconnect the wires and measure the primary + & - terminals.

oops fat fingered it when i was typing. i corrected it, should have read
Running volts at battery 13.5
Running volts at alternator 13.7
Running volts at ballast resistor 13.4

Maybe this is the problem ??

Nothing a set of 300.00 plug wires won't fix.
Just kidding.
